Flash 10 will be using OpenGL ES and optimized for OMAP3. Adobe and ARM are working on this. See http://www.adobe.com/aboutadobe/pres...dobeFlash.html

Amazon should say the S&H and tell you where the device is shipped from. If its coming from US you can be reasonably sure its a US version.

If not, it should be stated clearly.

If it isn't a US version while its sold from a US business residing in US, you receive the device, and you are not satisfied then you should be able to get a full refund because the advertisement was bad. There are very little differences between US and other versions except in case of N810 the keyboard might be different.

If in doubt save yourself the hassle, and ask the seller.

Amazon isn't fully world-wide. Maybe they mean 2nd hand devices. Sure, on eBay you should take care to read the auction. I bought my Nokia N810 in UK, and the only big problem was the adapter to load it up which doesn't work in EU. But most Nokia adapters simply work, and I had some spare adapters.
